Denon DP-59L skips at end of record

Good tip from Fleib. A word of caution on vintage turntables. Given the age it best to do a pick up and test when you buy, never ship, even if the seller has all the original packing materials and boxes. Parts for these vintage TT's are rare and finding someone to do the repair is almost an impossible feat, even if you have the service manual.

I like vintage tables, have had a Sony PX-7 for decades that still sounds great.
That said, I would not pay more for one than it would bother me to just throw it in trash.

If the auto lift or cueing bar is confirmed not hitting the tonearm, then check the anti-skating force and/or Vertical Tracking Force. Too much anti-skating force can make the tonearm want to jump back away from the center of the record. Is that what it is doing when it skips? Is the tonearm moving outward towards the outside of the record?

I did download the service manual but there is nothing specific about this. Can anyone give me guidance on how to repair the auto lift mechanism if that is the problem?

Did you determine that the arm isn't rubbing on the auto lift platform near end of record?

In the service manual there should be an exploded view of the arm and the automatic parts. If you can't find the adjustment screw and there's no picture of it, you might have to take it to a tech. It could be something else. You could try setting the damping and anti-skate to zero and make sure tracking force is correct and has a clean needle.

That table could be 30 years old. It's really impossible to diagnose or fix it long distance.
